What is the greatest source of scatter radiation during fluoroscopic procedures?

During fluoroscopic procedures, the greatest source of scatter radiation is the patient. When the x-ray beam is directed toward the patient for imaging, not all of the radiation is absorbed by the body; some of it interacts with tissues and gets scattered in various directions. This scattered radiation can then potentially expose both the medical personnel and anyone in the vicinity to radiation.

Understanding this phenomenon is crucial for implementing effective radiation safety measures. For example, both lead aprons and other shielding devices are used to protect technologists and other staff from this scatter radiation. The amount of scatter radiation produced is dependent on various factors such as the size of the patient, the type of procedure being performed, and the energy of the x-rays used. This is why it is essential to maintain proper techniques and precautions during fluoroscopic procedures to minimize radiation exposure.
